In recent years, Raman spectroscopy has been used to study biological tissues. However, the analysis of experimental spectra is still challenging, since most tissue components overlap significantly and it difficult separate individual components. New methods are needed that would allow for decomposition into evaluation their contribution. The aim our work possibilities multivariate curve resolution alternating least squares (MCR-ALS) method skin tissues in vivo. We investigated human...
The paper is devoted to the identification of skin tumors and interpretation their component composition based on multidimensional analysis Raman scattering spectral data dermoscopic images. dataset contains 65 samples malignant melanomas, 107 seborrheic keratoses, 166 nevi. multivariate curve resolution alternating least squares was performed for spectra extract profiles main components composition. obtained biochemical neoplasms were analyzed by gradient boosting method. Dermoscopic image...
The purpose of this study is to improve the efficiency early diagnosis endometrial cancer using analysis surface-enhanced Raman scattering (SERS) blood plasma. Blood plasma patients aged 22 79 years was investigated. included 95 women. All were divided into 3 groups: group 1 consists 29 women with adenocarcinoma, 2 − 31 polyp, – 10 hyperplasia. A control consisted 25 healthy SERS spectra dried samples studied on an experimental stand consisting a Photon-Bio RL785 spectrometric system based...
The luminescent properties of photocured aliphatic and aromatic network polycarbonate methacrylates, containing organic fluorescent dyad, have been studied. dyad molecule includes two photosensitive fragments—tetraarylimidazole with a hydroxyl group azomethinocoumarin—in each which excited state intramolecular proton transfer (ESIPT) occurs, leading to the appearance emissions: blue (450 nm) green (535 nm). It was established that ratio intensities these emissions depends very significantly...
The luminescent properties of photocured aliphatic and aromatic network polycarbonate methacrylates containing organic fluorescent dyad have been studied. molecule includes two photosensitive fragments – tetraarylimidazole with a hydroxy group azomethinocoumarin, in each which excited state intramolecular proton transfer occurs, leads to the appearance emissions - blue green. It was established that ratio intensities these depends on excitation wavelength, as well length, flexibility...
A two-stage polylactide modification was performed in the supercritical carbon dioxide medium using urethane formation reaction. The resulted synthesis of polymerizable methacrylate derivatives for application spatial 3D structuring by laser stereolithography. use allowed us to obtain first time oligomer-polymer systems form dry powders convenient further preparation polymer compositions photocuring. photocuring modified polymers stereolithography and two-photon crosslinking. Using...
The paper presents results of using a neural network classifier to analyze images malignant skin lesions obtained hyper-spectral camera. Using three-block VGG architecture, we conducted the classification set two-dimensional melanoma, papilloma and basal cell carcinoma, in range 530 – 570 600 606 nm, characterized by highest absorption melanin hemoglobin. sufficiency inclusion training limited spectral is analyzed. show significant prospects algorithms for processing hyperspectral data...
Changes of concentrations plasma free amino acids (PFAAs) is an essential feature protein metabolic abnormalities in cancer patients. In this study, we aim to decompose Raman spectra mixtures acids. The effect noise on the decomposition result investigated. experimentally measured and artificially simulated their are studied. As a method, Multivariate Curve Resolution–Alternating Least Squares (MCR-ALS) analysis used. It shown that one can evaluate concentration using pure results be used...
Comparative analysis of results determining the stress-strain state (SSS) a specimen with laying [± 45/90/03/90/± 45] Torayca T700 prepreg geometric dimensions 500 × 100 1.7 mm during its tension was performed. Stress concentrator hole diameter 14 located in center. The loading carried out on MTS Landmark test machine. load increased stepwise through interval ΔР = 10 kN until complete destruction sample, which occurred at P 97 kN. stress value determined by calculation method and...
Abstract The mass spectra of mono‐ and dimethylbicyclo[3,3,1]nonanes have been studied. In addition to the fragmentation bicyclic form molecular ion, latter appears dissociate from its monocyclic form. Structural isomers stereoisomers with essential differences in thermodynamic stability may be identified by quantitative their spectra. Stereoisomers a ‘boat’ conformation one cyclohexane rings shown differ ‘chair’ both virtue higher intensity odd‐electron ions for former.
